La Condenada Mine

Roman mine 'La Condenada' is located in the Cuenca town of Osa de la Vega, forming part of one of the most extensive and interesting mining complexes of lapis specularis in Castilla-La Mancha. From there the specular plaster or glass was extracted, which due to its size and transparency the Romans used as glass, exploiting and distributing the mineral from this area to the entire Empire. This mine has a labyrinthine plot and a development of almost a kilometer of underground route on three levels accessible to each other.
